v j 1 vBe it known that I, GARLAND Y. THOMP- son, a citizen of theUnited States, residing l. at 'Rossmoyna in the county of Hamilton i'"and `State of Ohio, have invented new and useful mprovements in FireEscapes, of which the following is a specification.

invention relates to lire escapes, and Vits primary object 1s to providea device of this character which 1s simple, durable and 'VVth 'the'above and other obl@CtS in View `the invention consists in theconstruction, 'combinationand arrangement of parts here- -inafterfully'described, claimed and illustrated i'n the accompanying drawing,whereln:

Figure 1 is a perspective view of a fire escape`constructed 1naccordance with my Y nal sectional view of the rope brake.

Referring to the drawing by reference numerals, 1 designates they mainrope, 2 the rope brake, 3 the supporting rope and 4 the l brakecontrolling rope of my improved fire escape.-

vkThe rope brake comprises a body 5, which f is curved longitudinallyand which' is pro'- *aoY videdat vits relativelyV lower end with arecess 6. A roller 7 1s journaled in the recess 6 and the side walls ofthe recess are pro- 'vided with perforations 8.

`shaped Vin cross-section, the longitudinal Y At a point adjacent itsrelatively upper end the body is provided with a slot 9 and angularlyprojectingv from itsV relatively upper end is a The jaw 10 issubstantially U- y'edges of the flanges 11 thereof being cut away, as at12. A pair of relatively spaced 9j. cylindrical members 13 are mountedupon f bolts 14 secured to the side flanges 11 of the j'aw10- Inpractice, the main rope 1 Vpasses through the slot 9, and to permit therope 45 brake to Ybe Vreadily and quickly applied to and removed fromthe main rope, one side wall of the slot 9-is provided with an open-*ing 15 through which the rope may be readily and quickly inserted intothe slot.

Toy prevent'the rope brake from becoming is secured in applied positionby means of a rivet, not shown. A'lever 18 is pivotally mounted at apoint between its ends in the .l Islot 9 by means of a bolt 19. Thelever is Specification of Letters Patent.

curved longitudinally and is provided with a plurality of perforationsthrough the medium of which the supporting rope 3 may be secured to thelever at different points. Projecting forwardly from the relativelyupper Aend of the lever 18, is a jaw 21 which is recessed, as at 22. Acylindrical member l 23 is located in the recess 22 and it is mountedupon a bolt secured to the side walls of seid recess. Then the jaws aremoved into closed or active positions, the member 23 occupies aposit-ion between the members 13, thereby frictionally clamping the mainrope, the cut away portions 12 of the flanges 11 permitting the member23 to be moved inwardly beyond the planes of the members 13.

The brake controlling rope is secured to the body 5 by having one of itsends passed through the perforations 8 and then secured to the rope inany suitable manner, and the controlling rope is secured to thesupporting rope by means of a rope section 26. Y

In practice, the main rope 1 is suspended at a suitable point outside ofthe building, the rope brake applied to the main rope, and thesupporting rope passed about the person at a point beneath the arms, thesupporting rope being secured about the person by means of a snap hook25. As the supporting rope 3 is secured to the relatively lower end ofthe lever 18 and passes over the roller 7, the weight of the person willmove the aws into closed or active positions, thus causing them tofrictionally engage the main rope. This frictional engagement of themain rope is so great that the person is suspended thereon.

TWhen it is desired to descend all that is necessary is to pulldownwardly on the brake controlling rope il, as thereby the jaws aremoved in opposite directions away from the main rope. It should beapparent that the person can readily and quickly control the speed ofhis descent. As the supporting rope can be secured. to the lever 18 atdifferent points, it should be apparent that the frictional engagementof the main rope by the jaws can be regulated. The rope section 26limits the opening movements of the jaws.

From the foregoing description taken in connection with the accompanyingdrawing, the construction and mode of operation of the invention shouldbe understood without a further extended description. j

Changes in the form, proportions and minor details of construction maybe made within the scope of the claims without departing from the spiritor sacrificing any ot tbe advantages oit the invention.

Having'fully described and illustrated my invention, what I claim is:

l. A tire escape including a. rope brake consisting of a body providedwith a slot, one oi the side walls of said slot being provided 'with anopening, a leaf spring` secured to the side wall and adapted to closethe opening'. a pair of relatively spaced members mounted on the jaw, alever pivotally mounted at u point between its ends in the slot of thebody, and a member mounted on the lever. y

A lire escape including a rope brake consisting of a body provided witha recess at one end and with a jaw at its other end,

said body being` provided with a slot having one of its side Wallsprovided With an open ing7 a leaf spring Secured to said side Wall andadapted to close the opening, a pair of relatively spaced membersmounted to the jaw of the body, a'lever provided with a jaw at. one endand with a plurality of spaced openings, said lever being pivotallymounted at a point between its ends in the slot of the body, and amember mounted on the jaw ot the lever.

In testimony whereof I atix my signature in presence ot' two witnesses.
